What are the spark plug models for the Spirior?

[LaEverly]

The spark plug model for the Spirior is NGK LZKR6B-10E. The spark plug is a crucial component in the ignition system of a gasoline engine. It introduces high voltage into the combustion chamber and generates a spark by jumping across the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. Under high voltage, the air between the center electrode and the side electrode of the spark plug rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties. This creates a discharge channel between the gap, resulting in a "breakdown" phenomenon. At this point, the gas forms a luminous body, known as a "spark." Along with thermal expansion, a "crackling" sound is also produced. The temperature of this electric spark can reach as high as 2000-3000°C, which is sufficient to ignite the air-fuel mixture in the cylinder's combustion chamber.
